Police commissioner Bill Bratton said it’s possible New York City could see a coordinated series of terrorist attacks similar to the ones in Paris Friday, and stressed the Big Apple remains their number one target.

“We work everyday based on the premise that [terrorists] have that capability,” Bratton told MSNBC’s Morning Joe.

“And what we just saw in Paris, why do we think that that would not happen here?”

Bratton said he plans to add an additional 500 cops to counterterrorism duties in the wake of the Paris massacre, which killed 129 people and wounded hundreds more in a coordinated series of shootings and bombings.

He said the fact that the terrorists picked targets like entertainment venues and restaurants says a lot about the message they are trying to send.

“All of the things the jihadists hate,” Bratton said. “And here we are, the financial capital of the world, the entertainment capital of the world, the news capital of the world — it is all that they hate, so we are the most likely target.”

The commissioner added that he will be sending a team of NYPD personnel to Paris to try and learn all they can about the methods employed by the terrorists, many of which Bratton said were unfamiliar to his cops.

“The idea that all of them were equipped with these suicide vests — which are of great concern if you’re asking your officers to rush in, which is the tactic here in America now in responding to the active shooter scenario,” he said.

“We’ll want to know the ballistic capabilities of those vests; how far do those projectiles spew out? In terms of the communications they used, what types of phones were they using? What type of apps were they using?”

Bratton said the communication devices used by the terrorists also pose a problem because they are nearly impossible to track because they are built to be so well encrypted, as are the apps they are using.

“They are going onto sites that we cannot access,” he said. “We are losing a lot of that intelligence momentum because of this issue.”

He also pointed to device and app manufacturers who intentionally design their products to be uncrackable.

“They need to work with us right now and in many respects they are working against us.”
